RECENT DEVELOPMENTS ON THE IFMIF/EVEDA BEAM DUMP COOLING CIRCUIT ∗

During the IFMIF/EVEDA activities a conical dump made of copper has been designed to stop the 125 mA, 9 MeV, D+ beam. This element will receive a total power of 1.125 MW. It is cooled by a high velocity water flow that circulates through an annular channel along the outer surface of the cone. The coolant composition must be defined taking into account corrosion and erosion phenomena. This work will present the influence of copper corrosion on the cone cooling parameters.
